Specificafion forming part of Letters Patent No. 144,685, dated November 18, 1873; application filed July 19, 1873.

,To all whom it may concer/n:

,useful Machine for Separating Broken -Up Weftsof Woven Cloth'from the VVarps thereof,or"brokenup warps from the wefts, as circumstances may require; and I do hereby declare the same to be fully described in the following specification and represented in the. accompanying drawings, of which- Figure l is a top view, Fig. 2 an elevation of one side, and Fig. 3 an elevation of the other side," of it. Fig. 4 is a longitudinal section of such machine.

Cloth to be treated by this machine is first to have each of the wefts or weitthreads broken or separated into many short lengths or pieces, so as to disconnect the warp-threads in a manner to admit of their'being readily separated from one another, and the fibers thereof untwisted and reduced to the state analogous to that in which they were before being spun, such being to enable them to be respun or used for other purposes in the arts. Cloth usually so' operated on has a woolen ,u warp and cotton weft, the latter being the part to be so broken.

In the drawing,` A denotes the frame of the machine, while B is an endless or feed apron arranged at the rear part thereof, and supported in two rollers, a b. In advance of the the main cylinder to the concave bar D, and

to a trough, K, extending underneath a toothed receiving-cylinder, L, arranged in advance of y the main cylinder, as shown.- In front of such cylinder L is a pair of feed-rollers, M N, and in advance of these is another main toothed cylinder, E, provided with a set of workers, F

F, a stripper, G, a chamber, H, grates I I, and a toothed receiving-cylinder, L, all like those hereinbefore described, there being next in advance lof the said cylinder L a rotary brush,

O. From each of the ch'ambersH there is an opening, c, leading into an intermediate space, I, open at bottom. To this space an airsuc tion apparatus may be applied to draw air down through the machine into the two chambers H H, and thence out of them by the openings c, such being to carry of, or aid in carryin g oli', the waste of the machine. Instead of Vusing the mechanism which is in advance of the `first receiving-cylinder L, I sometimes compose the machine of the rotary brush O and the mechanism in rear of the feed-rollers, thereby dispensing with the feed-rollers, the second main cylinder E, the second receivingcylinder, and the workers and strippers of such second main cylinder, in which case I apply the brush to the first receiving-cylinder L in the manner in which it is shown applied to the second cylinder L.

For operating the several toothed cylinders, feedingapron, brush, and feed-rolls, mechanism such -as represented is used-that is to say, on the shaft of the main toothed cylinder E first described is a fast pulley, d, anda loose pulley, e. There is also another pulley, f, on such shaft, about which pulley, and a similar pulley, g, on theshaft of the second main cylinder E, is an endless belt, h. Furthermore, around the main cylinder-shaft, and

a pulley, c', carrying a gear, k, an endless belt,

l, is arranged. The gear k engages with another gear, m, fixed on the shaft of the inner supporting-roller of the endless apron. On said shaft is another gear, n, which engages with a gear, o, on the shaft of the toothed roller c. Around the shaft of each of the main cylinders E E, and also about a pulley, p, xed on the shaft of the next adjacent stripper G, a crossed belt, g, runs. On the shaft of the second main cylinder E is apulley, r, about which and a pulley, s, a belt, t, extends. Agear, u, xed to the pulley s, engages with another gear, c, on the shaft of the lower of the feedrollers M N, upon whose shafts are connectinggears w w. The gear .fr engages with a gear, y, which engages with a gear, y', on the shaft of the receiving-roller L. On this latter shaft is a pulley, z, about which, and two pulleys, a b', V'fixed on the shafts of the rst set of workers, a belt, c', travels. The rotary brush gets its motion from an endless crossed belt, d, which goes around a pulley, e, on the shaft of the brush and another pulley, j", iXed on the shaft of the second main cylinder E. Furthermore, a belt, g', goes around a pulley, la', on the said main cylinder-shaft, and another pulley, i', carrying a gear, k', to engage with a gear, l', fixed upon the shaft of the front toothed cylinder L. Finally, an endless belt,

m', going about three pulleys, a o pf, ixed on the shafts of the said roller L, and the second set of workers, serves to impart motion to the latter. After laying the material upon the endless apron, the latter will convey it to the receiving toothed cylinder. In going through the machine, the long unbroken threads will be subject to the action of the toothed cylinders, by which they will be untwisted and A picked apart, the broken threads or wefts being separated and discharged. Finally, the warps reduced to loose fibers will be ejected from the machine by the rotary brush.

I make no claim to an endless apron, feedrollers, toothed cylinders, a tray, a comb, and a foraminous cover, arranged and combined as represented in the United States Patent No. 127,354, in which is described a machine for picking curled hair; in which machine the dust is thrown out of the foraminous cover or top of the machine, while the hair is being treated by the toothed cylinders and comb,I

and driven along the tray. In my machine I have no such tray, and I have but one feedapron and one rotary brush. To render my machine4 a duplication of the other would restrippers F F F F G G, grates I I I I, feed-A rollers M N, receiving toothed rollers L L, and rotary brush O, all arranged and operated, or provided with operative mechanism, substantially as specified.

2. The three chambers H H P, arranged and communicating as described, in combination with the grates I, the two series of workers and strippers FG, the main and auxiliary toothed cylinders E C L, the feed-rollers M N and apron B, and the rotary brush O, all arranged and provided with operative mechanism substantially as specified.
